What is the best practice for moddeling complex structures? Using a single mesh, multiple meshes or multiple objects?
You can make things as separate objects, if you'd like. When you do so, use parenting.
You can still do it as one mesh, its up to you how you want to go about things. Eventually, you'll use bones and you'll need to use parenting then.
